BOX-MAKING MACHINE.

Application filed September 19, 1918.

To all whom it may concern Be it known that we, VILLIAM HUGHES, a citizen of the United States, and a resident of Ma-plewood, in the county of Essex and State ofNew Jersey, and O'r'ro R. BIELER, a subject of the Emperor of, Germany, and a resident of Montvale, in the county of Bergen and State of New Jersey, have invented a new and Improved Box-Making Machine, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention. has in view are,-to increase the number ofboxes which may be produced in a given time; to reduce the cost of production of said boxes; to reduce the quantity of material used in the manufac ture of the boxes of the character herein disclosed; and to provide a smooth running machine for performing the mechanical operations necessary to produce the boxes.

manufacture of which the present machine is designed are what is known in thetrade as tray boxes or boxes wherein top-opening trays are placed in rectangular tubular cases or covers. The general idea of the cover is that shown'in Fig. 13 of the drawings, the case or cover being open at both ends.

l/Vhen operating the present machine, it will be understood" that blanks such as shown in Fig; 7 of the drawings are furnished. The blanks so furnished comprise scored cardboard pieces A, scoredlines B and C having been impressed thereon to provide bending lines therefor. Adhesively attached to each of the members A is a'paper facing D. The face D is so arranged that edge margins-E and F extend beyond the edges of the member A. These edge margins are furnished with a suitableadhesive before being placed in the machine upon the platen 20 to be operated upon by themachine.

The platen 20 is normally held by a supporting arm 21 flush'wi'th the operating table 22. The arm 21 is pivoted on; a shaft 23 and issupported by a cam 2-1 on the driven shaft 25. A wheel 26 tracks on the perimeter of the cam 24 and rocks the arm 21 to compress the spring27, as shown in Fig. 1 of the drawings, when the platen 20 is elevated as shown'in said figure.

The platen 20'is mounted at the end of a plunger 28 with the lifting pin 29 of which the arms of a yoke 30 on the arm 21' engage. The movement of the plunger 28 upward and downward is controlled by a pin 31 which extends through a slot 32 formed in the said plunger. The pinBl is mounted in a pendent frame 33 which is supported from the end of a table 3 1 and provides the bracket 35 in which the shaft is mounted.

WVhen the cam 24: permits, the spring 27 expands to depress the plunger 28 and the platen 20 at the upper end thereof. This movement of the arm 21 and platen 20 is perfectly timed with the operation of a plunger 36 and a sleeve 37 both of which are reciprocated by the functioning of the cams 38 and 39, the said cams being best shown in Figs. 1 and 1 respectively.

The plunger 36 and sleeve 37 are telescopically arranged, the former being discated yoke ends 46 and 47 respectively the jaws of which engage pins 48 and 49 set out from the upper ends of the plunger 36 and the sleeve 37. The said plunger and sleeve are both held in line and limited as to move-- ment by a pin 50 extending through the head of the bracket arm 40 and through slots 51 and 52 in the said plunger and sleeve. 7

By comparison of the cams 38 and 39. it will be noted that the keyways 53 therein are shown inthedrawings as in alinement. The riser 54 of the cam 38 precedes in point of time the riser 55 of the cam 39. The connecting rods 56 and 57 and the rollers 58 and 59 are alined, as shown in Fig. 1 of the drawings; therefore,.the roller 58 is lifted by the riser 54 to the cam level 60 before the roller 59 is lifted by the riser 55. This operation of the cam 38 depresses the plunger 36 and the foot 61 carried thereby upon the platen 20 and the blank A resting thereon.

This position of the foot 61 and plunger 36 is to be seen in Fig. 4 of the drawings. The cam 39 quickly operates the connecting rod 57 to rock the arm 45 to depress the sleeve 37 and the bracket block 62 carried thereby until the same rests directly above the foot 61. hen the plunger 36 was moved to press the foot 61 upon the platen 20, the said platen slightly depressed, suiiicient to permit the edges 63 of the opening in the table 22 to lift the edges E at the sides of the member A. When the sleeve 37 is depressed the cam level 64 holds the parts in position while the brush arms 65 are rocked on pivots 66 to advance wipers 67 over the edges of the member A, folding down the edges E E upon the said member A as the wipers are passed thereover.

The arms 65 are rocked by the operation of the cam 68 on a cam wheel 69, shown best in Fig. 1 It will be observed. that the cam 68 is a short and sharp cam which rocks the arm 7 O by means of the roller 71 thereon quickly to move the link 72 forward so that the arm 65 is swung toward. the foot 61. The arms. 64 and 65 are operatively connee-ted by a link 7 3 said link being pivotally connected to said arms at opposite sides of their respective pivots 66,thereby ii'nparting to the lower endof the arms and 65 rela --lever 71- of the cam '38 further rocks the arm 44 todepress the plunger 36 and the til the wheel 26 and roller 58 rest on the cam dwells 76 and 77 respectively. In this position the platen 20 and foot 61 are de pressed to the position indicated by broken lines in Fig. 4 of the drawings.

As seen in Fig. 4 of the drawings, the platen 20 approximates in width the width of the casing member A. As seen in Fig. 3 of the drawings, the length of the platen 20 equals the distance from the scored line Cto the second scored line B, beginning from the scored line C, on the said memberA. The length of the foot 61 is the same as the length of the platen 20. When the platen 20 and foot 61 are depressed through the opening in the table 22 the edges of said opening bend the member A upwardly on the said score lines C and B above pointed out, the edges E of the paper facing D having been folded over the adjacent edges of the member A. The position of the blank at this stage of the proceedings is shown.

in Fig. 10 of the drawings.

As seen best in Fig. 4 the platen '20 is brought to rest opposite the opening between the rollers 78 and 79. The opening between the rollers 78 and 7 9, as before seen in Fig. 3 of the drawings, is in line with a plunger plate 80. The plate 80 is moved toward the platen 20 and is cut away to form a rabbet shoulder 81 which extends over to lay the short outstanding-portion G formed from the member A when bent on the scored line C. This operation is performed during the period when the cam dwell 77 holds the foot 61 on the platen 20, which period inclicates immediately that the plate 80 has moved over the platen and the shoulder 81 has engaged the member A. The cam riser 82 of the cam 38 permits the rapid ascent of the plunger 36 and foot 61 to remove the said foot from the path of the advancing plate 80.

The plate 80 is pivotally connected by a pin 83 with a lever 84. The lever 84 is fulcrumed on a stud shaft 85 extending from the underside of the table 34. arm of the lever 84 has a roller 86 which tracks on the side of the cam wheel 69 in the path of a face cam 87. When the cam '87 rides under the roller 86. the free end of the lever 84 is moved toward the rollers 7 8 and 7 9 carrying the plate 80 in that direction. That portion of the member A extending between the scored line B and the end of the member A. having the edge F is elevated. hen. the plate 80 forces the member A be- The short tween the rollers 78 and 79, the upstanding portion is at once folded down and pressed as the folded member passes between the said rollers.

The roller 79 is driven by power transmitter through the bevel gears 88 and 89, the former being secured on the driven shaft A telescopic shaft having members 99 and 91 operatively connects universal joints 92 and 93, the latter of which is directly connected with the shaft 9% on which the roller 79 is mounted. The roller 78 is mounted in bearings on a rocking frame 95, the tail whereof is suspended on compression springs 96. The springs 96 rock the frame 95 so that pressure is constantly maintained by the roller 78 on the roller 79. It is evident that as soon as the folded member A is delivered to the said rollers the rotation of the roller 79 will carry the member A between the rollers 7 8 and 79 under the pres sure of the spring 96, and that, when in the course of the operation the edge F having its coating of adhesive overlies the short outstanding portion G the edge F is pressed thereon to cover the same. This action is best shown by reference to Fig. 11, which indicates the position of the parts as the product of the machine spreads between the rollers 78 and 79; while in Fig. 12 the prod not is shown as it is delivered from between the said rollers and from the machine. The function of the machine ceases at this point. Thereafter an operative unfolds the product to dispose the same in the manner shown in Fig. 13, in which position the casing is ready to receive the tray for which it is provided. v

It will be understood that the cam dwells 76 permit the spring 27 to hold the platen in its lowermost position until the plate 80 has been retracted from the upward path of the said platen. Also, the cam 24 is timed so that the rollers 78 and 79 will have removed the folded product from the path of the said platen prior to the wheel 26 riding to the highest level of the said cam 24' to lift the platen -20 to its initial receiving position. From this point the operation above de scribed is repeated.

The shaft 25 whichfurnishes power to the mechanism disclosed is driven by power imparted to a pulley 97 or, if desired, the said shaft is directly driven by some independent motive power.
